ACAP Summative Grade 6 Science is Alabama's spring statewide assessment (~66 items, ~60 blueprint points) with Level 1–4 results; Level 3+4 counts as proficient on state reporting.

Sample ACAP Science Grade 6 Practice Questions

Try these sample questions to test your ACAP Science Grade 6 exam readiness. Each question includes a detailed explanation. Start the interactive quiz above for the full 100+ question experience with AI tutoring.

1What primarily causes day and night on Earth?
A.Earth rotating on its axis once about every 24 hours
B.Earth revolving around the Sun once each day
C.The Sun moving completely around Earth each day
D.The Moon blocking sunlight for half of each day
Explanation: Earth spins on its axis roughly once every 24 hours. The side facing the Sun experiences day, and the side facing away experiences night. Revolution around the Sun takes about a year and does not cause the daily day-night cycle.
2Which statement BEST explains why Earth has seasons?
A.Earth is much closer to the Sun in summer and much farther in winter for both hemispheres at the same time
B.Earth's axis is tilted about 23.5°, so different hemispheres tilt toward the Sun at different times of year
C.The Moon's gravity tilts Earth toward the Sun every three months
D.Cloud cover blocks all sunlight in winter and none in summer worldwide
Explanation: Earth's tilted axis means that as Earth orbits the Sun, one hemisphere tilts toward the Sun (longer, more direct sunlight = summer) while the other tilts away (winter). Distance from the Sun is not the main cause of seasons.
3A student sees a full Moon. About how long will it be until the next full Moon?
A.About 29-30 days (roughly one lunar cycle)
B.About 12 hours
C.Exactly 7 days
D.Exactly 365 days
Explanation: The Moon completes a full cycle of phases (new Moon to new Moon, or full to full) in about 29.5 days. Seven days is only about one quarter of the cycle; a year and half a day are not phase periods.
4Which alignment produces a solar eclipse?
A.The Moon is between Earth and the Sun, casting a shadow on Earth's surface
B.The Sun is between Earth and the Moon
C.Mars is between Earth and the Sun
D.Earth is between the Sun and the Moon, casting a shadow on the Moon
Explanation: A solar eclipse happens when the Moon passes between Earth and the Sun and the Moon's shadow falls on Earth, blocking sunlight from a region. A lunar eclipse is when Earth is between the Sun and Moon.
5A lunar eclipse can be seen only when which condition is true?
A.The Moon is at first quarter and far from Earth's orbital plane
B.The Moon is between Earth and the Sun so the Moon's shadow falls on Earth
C.Venus is aligned with Earth and the Sun
D.Earth is between the Sun and the Moon so Earth's shadow falls on the Moon
Explanation: In a lunar eclipse, Earth lies between the Sun and Moon. Sunlight is blocked from reaching the Moon as it passes through Earth's shadow. This requires a full Moon near the orbital plane (eclipse season).
6Why does the Moon appear to change shape over a month even though it is always a sphere?
A.We see different portions of the Moon's sunlit half as its position relative to Earth and the Sun changes
B.The Moon melts and reforms each month
C.Clouds permanently cover parts of the Moon in a repeating pattern
D.Earth's atmosphere stretches the Moon into different shapes
Explanation: Half of the Moon is always lit by the Sun. As the Moon orbits Earth, our viewing angle of that sunlit half changes, producing the familiar phase cycle from new to full and back.
7Which force keeps planets in orbit around the Sun?
A.Wind pressure from solar flares only
B.Gravity between the Sun and the planets
C.Friction between empty space and planets
D.Magnetism from Earth's core only
Explanation: Gravity is the attractive force between masses. The Sun's gravity pulls planets inward while their orbital motion keeps them moving sideways, producing curved paths around the Sun.
8A student compares scale models. If the Sun is a basketball, Earth would be closest in size to which object?
A.A small bead or peppercorn (much smaller than the basketball)
B.A beach ball larger than the basketball
C.A house-sized sphere
D.Another basketball the same size as the Sun model
Explanation: The Sun's diameter is about 109 times Earth's. In classroom scale models, if the Sun is basketball-sized, Earth is only about a few millimeters across—like a small bead—emphasizing how much larger the Sun is than Earth.
9Planet data table: Planet | Average distance from Sun (AU) | Orbital period Mercury | 0.39 | 88 Earth days Earth | 1.00 | 365 Earth days Jupiter | 5.20 | about 12 Earth years Based on the data, which statement is BEST supported?
A.Planets farther from the Sun generally take longer to complete one orbit
B.Distance from the Sun has no relationship to orbital period
C.All planets take exactly one Earth year to orbit the Sun
D.Mercury takes longer to orbit than Jupiter
Explanation: The table shows orbital period increasing with average distance: Mercury is closest and fastest, Jupiter is farther and has a multi-year period. This pattern reflects how orbital speed and path length change with distance under gravity.
10Why do stars appear to move across the night sky over several hours?
A.Stars burn out and reform in new positions hourly
B.The Moon pushes stars westward each night
C.Stars orbit Earth once every few hours
D.Earth is rotating, so our viewpoint of the sky changes
Explanation: Earth's rotation causes the celestial sphere to appear to turn. Stars are extremely distant and do not orbit Earth on hourly timescales; the apparent motion is due to our spinning planet.

About the ACAP Science Grade 6 Exam

ACAP Summative Grade 6 Science is Alabama's required spring statewide summative assessment for grade 6 students, administered by the Alabama State Department of Education on the DRC INSIGHT platform. It measures the Alabama Course of Study: Science standards, which moved to the 2023 edition for the spring 2026 administration with mixed item types and timed sessions. Practice questions on OpenExamPrep are free English-language multiple-choice study aids aligned to the official reporting categories; they do not replace authentic constructed responses, listening tasks, technology-enhanced items, or the secure official assessment. ALSDE permits Spanish-language science forms for eligible English learners until English proficiency is attained; this practice bank is English only.

Frequently Asked Questions

What is the ACAP Summative Grade 6 Science assessment?

It is Alabama's required spring Science summative for grade 6, part of the Alabama Comprehensive Assessment Program (ACAP) Summative run by ALSDE on DRC INSIGHT.

Is the official test all multiple choice?

No. Official ACAP Summative uses multiple item types (including multiple-select and technology-enhanced items, and for ELA text-dependent writing). This site offers English four-option MCQ study adaptations only.

How long is the official test?

About 90 minutes total (two sessions of ~45 minutes each per the ALSDE ACAP Summative Test Times and Item Counts table).

How many questions are on the official test?

The ALSDE Test Times and Item Counts table lists about 66 items for this grade/subject; the 2024 blueprint allocates 60 possible points across reporting categories.

What do scores mean?

Students receive four achievement levels (Level 1–Level 4). Alabama proficiency reporting treats Level 3 and Level 4 as proficient.

Is there a testing fee?

No family fee for eligible public school students; districts administer the required state assessment.

When is ACAP Summative given?

Once each spring. For 2025–26, ALSDE scheduled ACAP Summative Grades 2–8 for March 16–April 24, 2026, with Grades 2–3 ELA required in the first four weeks of the window.

Did the science standards change recently?

Yes. Alabama adopted the 2023 Alabama Course of Study: Science, implemented in 2025–26. ALSDE reported that spring 2026 was the first administration testing the new standards, with results based on new cut scores, so science scores are not directly comparable to earlier years.
